I have a bottle on mine to trap the oil. You can always feel some slight pressure coming out, I think it's probably normal since I'm not using any oil worth noting between changes. 53K miles.

I'm not sure about a Cummins,but on a Mercedes-Benz diesel the recomended method to check for a bad valve is to put a pressure gauge to the blow off hose. Anything over 5 psi indicates a problem. 5 psi is more than a slight pressure,with your thumb over the end of the hose you can make it fart,for lack of a better word.
